How to Check Your Wifi GHZ on iPhone?

Most of the WiFi routers today support both 2.4 GHz and 5 GHz connectivity. That is perhaps why it becomes quite important to check which GHz your iPhone is connected to. This can affect your internet speed, interference level, and WiFi range. But, you do not know how to check your WiFi GHz on iPhone? Well, we will help you find out how. 

Finding which GHz your iPhone is connected to is easy. Simply go to your Settings app, select WiFi and check whether your iPhone is connected to 2.4 GHz or 5 GHz. Your Wi-Fi network name should let you know the band that your iPhone is connected to. 

What is WiFi GHz?

WiFi GHz is the network frequency band that your WiFi routers transmit the network to in wireless mode. The speed with which the data is sent or received over the Wi-Fi network is represented in GHz. The Wi-Fi networks operate in 2.4 GHz and 5 GHz frequency band modes. 

Having a knowledge of the GHz frequency band that your iPhone connects to can help you resolve the signal strength and internet speed issues. It will also provide you with an idea of which band your phone is capable of connecting.

How to Check Your WiFi GHz on iPhone?

There are different ways that you can work to check your Wi-Fi GHz on your iPhone. 

Method 1: Check your WiFi Network name 

If you have a dual-band router, you can easily check which band your phone is connected to. Follow the steps here below:

  • Go to your Settings app
  • Tap on the WiFi option
  • Locate and tap on your WiFi name

The network name should indicate whether you are connected to the 2.4 GHz or 5 GHz band. 

Method 2: Airport Utility app 

The Airport Utility app is one of the excellent options to help you check which network band your iPhone is connected to. In fact, the Airport Utility app is designed to work with the Apple routers. However, you can use the Airport Utility app even when you are not on the Apple Router. 

Here are the steps you can use for finding the GHz on your iPhone through the Airport Utility app:

  • Go to your App store
  • Install the Airport Utility app
  • Navigate to Settings ->Airport Utility
  • Toggle the option for WiFi Scanner
  • Open the Airport Utility app
  • Tap on WiFi scan in the top right corner
  • Tap Scan to find all the networks available
  • Check the number next to the Channel.

If you find the Channel number between 1 and 11, you are connected to 2.4 GHz. If you find the channel numbers above 12, you are connected to the 5 GHz network band.

2.4 GHz vs 5 GHz – Which Is Better?

The primary difference between the 2.4 GHz and 5 GHz is the speed, range, signal strength, and interference levels. 2.4 GHz offers a better coverage range, while the speed may be a little less. 5 GHz offers better speed, but it will have a lower range. 

2.4 GHz vs 5 GHz

The major difference between the 2.4 GHz and 5 GHz lies in…

  • Speed: The 2.4 GHz does not offer much speed when compared to the 5 GHz. However, it suffers interference. 
  • Range: The 2.4 GHz goes through a long distance. It can also move through obstacles. In contrast, the 5 GHz frequency band offers just a shorter range. It will also face barriers such as walls and obstacles. 
  • Congestion: Multiple devices share the 2.4 GHz frequency band. This will cause network congestion. It is more prone to interference and congestion. The 5 GHz band is less crowded, and there would be lower interference from other devices. 
  • Support for older devices: When it comes to support for older devices, the 2.4 GHz is one of the best. Older devices may not support the 5 GHz band. 
  • Concurrent connections: 5 GHz provides you with an option to connect to more concurrent devices. If you have multiple devices at home, the 5 GHz band is the right option for you.

Can You Manually Change Between 2.4GHz and 5GHz Wi-Fi Bands on iPhone?

No, the iPhone does not let you manually change between the 2.4 GHz and 5 GHz bands. Your phone will connect to the best networks based on the speed. The choice between 2.4 GHz and 5 GHz is made based on the signal strength and the speed obtained on the iPhone. 

In fact, iOS devices are made to connect to the 5 GHz band when they are closer to the router in order to achieve better speeds. If you travel farther from the 5 GHz signal, your iPhone will switch to 2.4 GHz automatically. 


Checking GHz on an iPhone is always a good idea. Knowing which network or which band you are connected to can help you switch to a better network. You will be able to connect to a better frequency based on your individual preferences and requirements. 

There are different ways that you can check WiFi GHz on an iPhone. Use the right options that best meet your requirements and enjoy the best network performance on your device. 


Should I use 2.4 GHz or 5 GHz Wi-Fi? 

The choice between 2.4 GHz and 5 GHz should largely be based on your individual preferences. 2.5 GHz offers you a better range and less barriers, but you get a lower speed. On the other hand, the 5 GHz band offers higher speed, while it may not offer you a better range. 

Does the iPhone Support the 6GHz Network Band?

No, as of now, no iPhone model supports 6 GHz. In fact, the 6 GHz band is quite new and is not yet available on most of the devices. In fact, we have not found any routers as well that would support the 6 GHz band. 

Does 2.4 or 5GHz Wi-Fi go through walls?

2.4 GHz band can easily penetrate the walls and buildings. However, the 5 GHz band will not be able to go through the walls and some physical barriers.
